ShaH-IOL
tester provides fast and accurate quality control of intraocular
lenses (IOL) with a spherical, aspheric, toric, or complex
surface. Measurement and wavefront analysis allow receiving in a
few seconds the complete information on the optical quality of
an IOL: focal power, wavefront aberration map (up to 66 Zernike
polynomials), PSF (point spread function), MTF (modulation
transfer function), EFL (effective focal length). By means of
ShaH-IOL, it
is possible to analyze both monofocal and multifocal lenses,
either in dry (in air) or wet (in situ) conditions.

Intraocular lenses are being implanted into human eyes to
replace crystalline lenses in patients suffering from defects of
vision. Implantation of an IOL should provide the patient with
accurate vision of surrounding objects. Quality control is a
crucial point for choosing the individual IOL perfectly matching
the peculiarities of patient's vision system.
